The Stockholm archipelago is the largest archipelago in Sweden, and the second-largest archipelago in the Baltic Sea .GeographyThe archipelago extends from Stockholm roughly 60km to the east. In a north–south direction, it mainly follows the coastline of the Södermanland and Uppland provinces, reaching roughly from Öja island, south of Nynäshamn, to Väddö, north of Norrtälje. It is separated from Åland by a stretch of water named South Kvarken. A separate group of islands lies further north, near the town of Öregrund. Between Arholma and Landsort there are approximately 24,000 islands and islets. Some of the better-known islands are Dalarö, Finnhamn, Nässlingen, Grinda, Husarö, Ingarö, Isö, Ljusterö, Möja, Nämndö, Rödlöga, Tynningö, Utö, Svartsö and Värmdö.
